1. General Description
Apr, 2010
This manual is describes the Himax’s HX8353-D 132RGB*162 dots resolution driving
controller. The HX8353-D is designed to provide a single-chip solution that combined
a gate driver, a source driver, power supply circuit, and internal graphics RAM for
262,144 colors to drive a TFT panel with 132RGB*162 dots at maximum.
The HX8353-D can be operated in low-voltage (1.65V) condition to the interface and
integrated internal boosters that produce the liquid crystal voltage, breeder resistance
and the voltage follower circuit for liquid crystal driver. In addition, The HX8353-D also
supports various functions to reduce the power consumption of a LCD system via
software control.
The HX8353-D is suitable for any small portable battery-driven product and requiring
long-term driving capabilities, such as small PDAs, digital cellular phones and
bi-directional pagers.
